I'm trying to build Qt 5.3 rc1 statically on Windows w/ *desktop* OpenGL

Is this configuration supported?

This sounds similar to a problem I have in 4.8.5 with OSX 10.9. setFocus

Here is another regression I found that is a show-stopper for us.
In a custom widget I have a keyPressEvent() and keyReleaseEvent()
handler to update a cursor when modifier keys are pressed (such as Cmd).
In Qt 5.x, pressing Cmd (or shift, or ctrl) causes no keyPressEvents

Whether it's right or wrong, this code has worked for 10 years, and

Sure. lighter() multiplies the values of the color by the scale factor
